Behavioral Genetics - An introduction to how genes and environments interact through development to shape differences in mood, personality, and intelligence.pdf

Taken from Introduction: Why do humans range so widely in their susceptibility to mental illness, in their willingness to take risks, and in their performance on intelligence tests? One answer to this question comes from scientists in the field of behavioral genetics. They say that the variation in behavioral traits across a population is due, in part, to the genes. So many studies have pointed to connections between genes and particular behaviors that most scientists now feel comfortable stating that there is such a link for every possible behavior. But what does it really mean to say that there is a link between genes and behavior?
Does it mean that there is a gene that makes some of us blush when embarrassed; that there is one gene that makes you prefer classical music and another gene that makes you dislike it; that there is a bunch of genes that each provides for different levels of skill in playing poker? The answer to all these questions is no. Does it mean behavior passes down from generation to generation, i.e., is inherited, just like baldness and eye color? Again, the answer is no.
So when next you see an article that proclaims, “Gene for [insert a human behavior here] discovered,” read it with a critical eye. Or when you next hear someone say, “He inherited his [insert a human behavior here] from his father,” receive that with skepticism, too.
The pervasive role of genes in behavior does not mean what it is commonly misunderstood to mean. It does not mean that a gene or even several genes can make you act in any particular way. It does not mean that a behavior can “pass down through the genes.” Such claims are not accepted in behavioral genetics.
It does mean that genes play a vital role in the body’s development and physiology, and it is through the body, acting in response to and upon surrounding environments, that behavior manifests itself. So while we do inherit our genes, we do not inherit behavior traits in any fixed sense. The effect of our given set of genes on our behavior is entirely dependent upon the context of our life as it unfolds day to day.

The purpose of this report is to spell out some of the prospects for control in the current and future technological environment, to describe the role the field will play in military, commercial, and scientific applications over the next decade, and to recommend actions required to enable new breakthroughs in engineering and technology through application of control research.

Computational Cognitive Science.pdf

Human learning and reasoning is founded on multiple knowledge representations with different kinds of structures, such as trees, chains, dominance hierarchies, neighborhood graphs, and directed networks. This class uses probabilistic inference methods from machine learning and Bayesian statistics, operating over different kinds of structured representational systems, to explain how people’s domain knowledge can support a wide range of learning and reasoning tasks, and how these knowledge structures may themselves be learned from experience.
